I can see the nostalgia aspect of an old bike to ride over to the store or a restaurant, but bikes in general just keep getting better and better from a performance point of view. When I buy a new bike, it is because it is noticeably better than what it replaced. My Specialized Stumpie Evo Carbon whatever kills my GT Zaskar and my Roubaix SL4 Disc Pro whatever kills my Fuji Gran Fondo. Both perform better in every way and are about 4-5 years apart in age. My 2014 Stumpie is amazingly different than my 84 Stumpie.
So, other than memories, why all of the attention on old bikes? And, for later, why on earth does Specialized feel the need for so much whatever to follow each name???
This is sincere curiosity, so please leave insincere responses until later
